RESUMO

BACKGROUND: Routine childhood vaccination is among the most cost-effective, successful public health interventions available. Amid substantial investments to expand vaccine delivery throughout Africa and strengthen administrative reporting systems, most countries still require robust measures of local routine vaccine coverage and changes in geographical inequalities over time. METHODS: This analysis drew from 183 surveys done between 2000 and 2016, including data from 881 268 children in 49 African countries. We used a Bayesian geostatistical model calibrated to results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2017, to produce annual estimates with high-spatial resolution (5 ×    5 km) of diphtheria-pertussis-tetanus (DPT) vaccine coverage and dropout for children aged 12-23 months in 52 African countries from 2000 to 2016. FINDINGS: Estimated third-dose (DPT3) coverage increased in 72·3% (95% uncertainty interval [UI] 64·6-80·3) of second-level administrative units in Africa from 2000 to 2016, but substantial geographical inequalities in DPT coverage remained across and within African countries. In 2016, DPT3 coverage at the second administrative (ie, district) level varied by more than 25% in 29 of 52 countries, with only two (Morocco and Rwanda) of 52 countries meeting the Global Vaccine Action Plan target of 80% DPT3 coverage or higher in all second-level administrative units with high confidence (posterior probability ≥95%). Large areas of low DPT3 coverage (≤50%) were identified in the Sahel, Somalia, eastern Ethiopia, and in Angola. Low first-dose (DPT1) coverage (≤50%) and high relative dropout (≥30%) together drove low DPT3 coverage across the Sahel, Somalia, eastern Ethiopia, Guinea, and Angola. INTERPRETATION: Despite substantial progress in Africa, marked national and subnational inequalities in DPT coverage persist throughout the continent. These results can help identify areas of low coverage and vaccine delivery system vulnerabilities and can ultimately support more precise targeting of resources to improve vaccine coverage and health outcomes for African children.

RESUMO

Genetic association studies of prostate and other cancers have identified a major risk locus at chromosome 8q24. Several independent risk variants at this locus alter transcriptional regulatory elements, but an affected gene and mechanism for cancer predisposition have remained elusive. The retrogene POU5F1B within the locus has a preserved open reading frame encoding a homolog of the master embryonic stem cell transcription factor Oct4. We find that 8q24 risk alleles are expression quantitative trait loci correlated with reduced expression of POU5F1B in prostate tissue and that predicted deleterious POU5F1B missense variants are also associated with risk of transformation. POU5F1 is known to be self-regulated by the encoded Oct4 transcription factor. We further observe that POU5F1 expression is directly correlated with POU5F1B expression. Our results suggest that a pathway critical to self-renewal of embryonic stem cells may also have a role in the origin of cancer.

RESUMO

OBJECTIVES: Diseases of the heart and malignant neoplasms (all-cancers) are the leading causes of death in the United States. The gap between the two has been closing in recent years. To assess the gap status in Texas and to establish a baseline to support evaluation efforts for the Cancer Prevention Research Institute of Texas, mortality data from 2006 to 2009 were analyzed. METHODS: Immediate cause of death data in Texas for the years 2006-2009 were analyzed and rates developed by sex, race/ethnicity, and four metropolitan counties. RESULTS: Overall, for the years 2006-2009, the age-adjusted mortality rates (AARs) among Texas residents for both diseases of the heart and all-cancers decreased; however, during this time frame, there was greater improvement in diseases of the heart AARs as compared with all-cancers AARs. For the four large metropolitan counties of Bexar, Dallas, Harris, and Travis, data were analyzed by sex and race/ethnicity, and 11 of the 12 largest percent mortality rate decreases were for diseases of the heart. CONCLUSIONS: Age-adjusted mortality rates among Texas residents from diseases of the heart are showing improvement as compared with the rates for all-cancers.

RESUMO

This literature review aims to provide an analysis of the current trends in at-sea medical evacuations (medevacs), with the objective of providing insights to decision-makers to improve patient outcomes. Sixteen sources spanning diverse research methodologies were employed for data collection. The findings point to medical disease processes outweighing trauma and psychiatric conditions as the primary justifications for medical evacuations in the international maritime community. In particular, suspected cardiovascular pathologies emerge as the most prevalent grounds for recommended evacuations, underscoring the impact of their diagnosis and treatment in maritime healthcare scenarios. Enhancing the capabilities of on-site maritime healthcare providers to obtain cardiovascular diagnostic data to facilitate shoreside interpretation is proposed to mitigate the speculations inherent to long-distance medevac decisions. Furthermore, existing research indicates that sustaining a proactive approach focusing on pre-voyage health screenings for seafarers and passenger vessel patrons holds promise in minimizing the risk of emergency evacuations resulting from the exacerbation of chronic medical conditions. This review reveals that while a limited portion of the cruise ship industry possesses established tactical medevac data on crucial aspects of patient care (such as transportation delay, pre- and mid-transport level of care, and ultimate patient outcomes), there exists a dearth of equivalent informatio-n for comparable maritime communities. This knowledge gap necessitates further exploration and research to understand and address diverse seafaring populations' unique challenges. In conclusion, this literature review holistically examines the landscape of at-sea medical evacuation statistics. By assimilating the collective knowledge gleaned from internationally sourced data, this study underscores the urgent need for continued research, comprehensive data collection, and strategic interventions to optimize patient care, enhance tactical decision-making, and ultimately shape a more resilient and responsive healthcare network for maritime communities worldwide.

RESUMO

BACKGROUND: There is variability in intensive care unit (ICU) resources and staffing worldwide. This may reflect variation in practice and outcomes across all health systems. AIM: To improve research and quality improvement measures administrative leaders can create long-term strategies by understanding the nature of ICU practices on a global scale. METHODS: The Global ICU Needs Assessment Research Group was formed on the basis of diversified skill sets. We aimed to survey sites regarding ICU type, availability of staffing, and adherence to critical care protocols. An international survey 'Global ICU Needs Assessment' was created using Google Forms, and this was distributed from February 17th, 2020 till September 23rd, 2020. The survey was shared with ICU providers in 34 countries. Various approaches to motivating healthcare providers were implemented in securing submissions, including use of emails, phone calls, social media applications, and WhatsApp™. By completing this survey, providers gave their consent for research purposes. This study was deemed eligible for category-2 Institutional Review Board exempt status. RESULTS: There were a total 121 adult/adult-pediatrics ICU responses from 34 countries in 76 cities. A majority of the ICUs were mixed medical-surgical [92 (76%)]. 108 (89%) were adult-only ICUs. Total 36 respondents (29.8%) were 31-40 years of age, with 79 (65%) male and 41 (35%) female participants. 89 were consultants (74%). A total of 71 (59%) respondents reported having a 24-h in-house intensivist. A total of 87 (72%) ICUs were reported to have either a 2:1 or ≥ 2:1 patient/nurse ratio. About 44% of the ICUs were open and 76% were mixed type (medical-surgical). Protocols followed regularly by the ICUs included sepsis care (82%), ventilator-associated pneumonia (79%); nutrition (76%), deep vein thrombosis prophylaxis (84%), stress ulcer prophylaxis (84%), and glycemic control (89%). CONCLUSION: Based on the findings of this international, multi-dimensional, needs-assessment survey, there is a need for increased recruitment and staffing in critical care facilities, along with improved patient-to-nurse ratios. Future research is warranted in this field with focus on implementing appropriate health standards, protocols and resources for optimal efficiency in critical care worldwide.

RESUMO

The abundance of both taxonomic groups and gene categories in microbiome samples can now be easily assayed via various sequencing technologies, and visualized using a variety of software tools. However, the assemblage of taxa in the microbiome and its gene content are clearly linked, and tools for visualizing the relationship between these two facets of microbiome composition and for facilitating exploratory analysis of their co-variation are lacking. Here we introduce BURRITO, a web tool for interactive visualization of microbiome multi-omic data with paired taxonomic and functional information. BURRITO simultaneously visualizes the taxonomic and functional compositions of multiple samples and dynamically highlights relationships between taxa and functions to capture the underlying structure of these data. Users can browse for taxa and functions of interest and interactively explore the share of each function attributed to each taxon across samples. BURRITO supports multiple input formats for taxonomic and metagenomic data, allows adjustment of data granularity, and can export generated visualizations as static publication-ready formatted figures. In this paper, we describe the functionality of BURRITO, and provide illustrative examples of its utility for visualizing various trends in the relationship between the composition of taxa and functions in complex microbiomes.

RESUMO

BACKGROUND: For patients in whom laparoscopic adjustable gastric band has failed, conversion to Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy are both options for further surgical treatment. There are limited data comparing these 2 procedures. The National Bariatric Surgery Registry is a comprehensive United Kingdom-wide database of bariatric procedures, in which preoperative demographic characteristics and clinical outcomes are prospectively recorded. OBJECTIVES: To compare perioperative complication rate and short-term outcomes of patients undergoing single-stage conversion of gastric band to Roux-en-Y gastric bypass or laparoscopic sleeve gastrectomy. SETTING: United Kingdom national bariatric surgery database. METHODS: From the National Bariatric Surgical Registry data set, we identified 141 patients undergoing single-stage conversion from gastric band to either gastric bypass (113) or sleeve gastrectomy (28) between 2009 and 2014, and analyzed their clinical outcomes. RESULTS: With respect to perioperative outcomes gastric bypass was associated with a higher incidence of readmission or reintervention postoperatively (16 versus 0; P = .04). There was no difference in percentage excess weight loss between sleeve gastrectomy and gastric bypass at final follow-up at 1 year (52.1% versus 57.1% respectively; P = .4). CONCLUSIONS: Conversion from band to sleeve or bypass give comparable good early excess weight loss; however, conversion to sleeve is associated with a better perioperative safety profile.

RESUMO

A 68-year-old woman presented to the emergency department, with an abscess in the right upper anterior abdominal wall. She had a medical history of an open cholecystectomy 20 years prior, diabetes, obesity and a laparotomy for perforated sigmoid diverticular disease complicated by a large parastomal hernia. CT revealed this subcutaneous abscess to track intra-abdominally through the liver and communicate with the gallbladder fossa. The abscess was incised and drained. The wound initially drained pus, and then bile. Magnetic resonance cholangiopancreatogram (MRCP) demonstrated a remnant gallbladder containing 2 gallstones, a cholecystocutaneous fistula, portal vein thrombosis and cavernous transformation of the bile duct. The patient improved and was discharged. The patient's case history and imaging were discussed with the tertiary referral centre, in a multidisciplinary team. After an extensive and balanced discussion, the patient declined a completion cholecystectomy and continues to have occasional discharge from the fistula in her right upper quadrant.

RESUMO

CD248 (Endosialin) is a type 1 membrane protein involved in developmental and pathological angiogenesis through its expression on pericytes and regulation of PDGFRß signalling. Here we explore the function of CD248 in skeletal muscle angiogenesis. Two distinct forms of capillary growth (splitting and sprouting) can be induced separately by increasing microcirculatory shear stress (chronic vasodilator treatment) or by inducing functional overload (extirpation of a synergistic muscle). We show that CD248 is present on pericytes in muscle and that CD248-/- mice have a specific defect in capillary sprouting. In contrast, splitting angiogenesis is independent of CD248 expression. Endothelial cells respond to pro-sprouting angiogenic stimulus by up-regulating gene expression for HIF1α, angiopoietin 2 and its receptor TEK, PDGF-B and its receptor PDGFRß; this response did not occur following a pro-splitting angiogenic stimulus. In wildtype mice, defective sprouting angiogenesis could be mimicked by blocking PDGFRß signalling using the tyrosine kinase inhibitor Imatinib mesylate. We conclude that CD248 is required for PDGFRß-dependant capillary sprouting but not splitting angiogenesis, and identify a new role for CD248 expressed on pericytes in the early stages of physiological angiogenesis during muscle remodelling.
